This invention is directed to an improvement in hand oilers of the type wherein, through the manipulation of handle-carried parts, the oil in the container is ejected through the spout at will.

Hand oilers of this type include a pump positioned within the container and a lever mounted on the handle to be operated to actuate the pump. The connection between the pump proper and spout extends through that portion of the handle ordinarily provided with means for closing the end of the container and this connection includes a pipe section of reduced diameter to increase the pressure and speed of flow, with means between this reduced pipe and spout so that the parts may be connected against leakage and to properly position and support the pump within the container.

Heretofore the connection between the pump pipe and spout has been constructed in two or more parts united by soldering and as the connection must aiford a non-leaking passage for the oil and also provide a support for the pump parts, it has been found that under ordinary usage to which the oiler is subjected there has been a tendency to breakage or disconnection at the soldered joint which quickly renders the oiler as a whole inoperative for the purpose for which it was designed. Furthermore, the manufacture of the parts making up the connection and the independent and necessarily careful soldering of the joint requires several operations which have to be carefully carried out and at best tend to a rather limited life of maximum efiectiveness of the oiler.

It is the primary object of the present invention to provide the connection between the pump proper including the pump pipe and the spout as an integral indivisible part which, when assembled, avoids the possibility of breakage or disconnection tending to leakage and inoperativeness and further insures the possibility of a rapid, uniform and proper assemblage of the parts to properly position the pump within the container and insure a removable connection of the spout which may be effectively sealed in a convenient, conventional manner.

A further object of the invention is the provision of means for removably supporting the pump-operating lever on the handle with a view to simplifying the connection and at the same time permitting the rocking operation of the handle necessary to pump operation.

The invention is illustrated in the accompany- ,i g drawing, in which:

Figure 1 is a view in side elevation, partly in section, showing the integral connection forming the subject-matter of the present invention in applied position and illustrating the pumping mechanism and handle in cooperative relation.

Figure 2 is a broken vertical section through the integral connection between the piston of the pumping mechanism and the spout forming the subject-matter oi the present invention.

Figure 3 is a transverse section taken immediately above the enlarged portion of the handle to show the cooperation of the attachment and the opening in the enlarged portion of the handle to predetermine the position of the attachment.

Figure 4 is a broken perspective view showin the handle and lever, with the connecting means to permit relative movement of the lever, the parts being shown separated.

A pump assemblage of this character includes a pump involving a cylinder and a plunger, a pipe connected to the movable pump part, in the present case the cylinder, with such pipe of relatively reduced diameter, a spout through which the fluid delivered from the pump through the pipe is ejected, a lever mounted for rocking movement on the handle, and a separable connection leading from the lever to the movable part of the pump.

As illustrated in the accompanying drawing, the pump part is made up of a cylinder l, a hollow plunger 2 operative therein, the bottom of the pump, which extends into the container, being formed in any conventional or desired manner with an inlet, non-outlet valve mechanism. A handle 3 is provided which has a horizontal portion overlying the container and terminating at one end in an enlargement i to the under surface of which is secured in any appropriate manner a hollow threaded plug 5 which seats in and seals the opening in the upper end of the container.

Removably though securely fixed to the plunger 2 is a feed pipe 6 of materially less diameter than that of the plunger to insure increased speed and pressure of the fluid delivered in the operation of the pump. This feed pipe is diametrically enlarged at an appropriate distance from the plunger to provide a locking section l which is exteriorly threaded. Above the locking section, the feed pipe is further diametrically enlarged at 8 to provide between the sections 1 and 8 a limiting shoulder 9. Above the enlargement 8, the extended pipe section is further slightly increased in diameter to provide a positioning section it and above the positioning section, the

ill

pipe extension is further enlarged diametrically and exteriorly threaded to provide a spout-receiving section II.

The handle enlargement 4 and the bottom of the plug 5 are formed with vertically aligned openings I2 and I3 respectively through which the pipe extension is passed in the assemblage of the parts and the relation of the vertical dimensions of the parts is such that when in proper position the positioning section In fits within the opening I2 in the handle enlargement 4, allowing the spout-receiving section to rest squarely upon the upper surface of the handle enlargement and extend wholly above the same. The enlargement 8 of the handle section extends within the plug, terminating approximately in line with the bottom wall of the plug, while the threaded locking section 7 extends through and below the bottom wall of the plug.

In this type of oiler, in order to afford as complete a delivery as possible of the contents of the container, the pump proper is inclined to the vertical so as to terminate adjacent the wall of the container near the bottom and to thus position the pump proper, the feed pipe intermediate the plunger and locking section is slightly curved or bent to properly position the pump proper. As it is desirable and important that this positioning of the pump proper be maintained in the assembly, the feed pipe extension is formed to insure this position of the pump proper by providing the opening I2 with a fiat portion I4 and in further flattening a corresponding portion of the positioning section Ill of the feed pipe extension, as at I5. Thus, the feed pipe extension can only be assembled with the handle in one position, and in this position the pump proper is arranged at a proper inclination within the container.

A look nut I6 is loosely positioned on the feed pipe prior to the connection of the latter to the plunger, which look nut is designed to engage the locking section 7 in the assemblage of the parts and bind or look the feed pipe and feed pipe extension snugly between the bottom of the plug 5 and the top of the enlargement 4 of the handle, the lock nut engaging the bottom of the plug and the shoulder formed by the juncture of the spout-receiving section II and the positioning section bearing squarely upon the upper surface of the handle enlargement.

Obviously, in the assemblage, the feed pipe and feed pipe extension are passed through the handle enlargement l and plug 5 from above, the lock nut loosely positioned upon the feed pipe proper and the plunger connected, and as in"this assemblage the fiat portion of the feed pipe extension I5 cooperates with the fiat portion of the wall of opening I2 in the handle enlargement 4, the feed pipe and feed pipe extension are not only properly positioned to maintain the pump proper at the desired angle but held against rotative movement. A look nut I6 is then threaded on the locking section I and tightened to rigidly unite the parts with the handle.

It is to be particularly understood that the feed pipe and extension are a single integral part. There is no joint requiring soldering or other fixing and hence no possibility of leakage or breakage notwithstanding the continuous and hard usage of the oiler. There is an integral unit which extends from the plunger of the pump proper to the spout and hence liability of any leakage or any breakage is entirely and wholly obviated. This feed pipe unit, so-called, is of course independently constructed as a unit by proper machining in the usual manner and when completed affords not only a completely effective non-leaking, uninterrupted connection between the pump proper and the spout but provides a connection which presents the maximum protection against breakage or leakage and which, through its unit construction, is readily and conveniently assembled and may be as conveniently removed in disassembling the parts.

The integral feed pipe extension is of course formed with a longitudinal bore I! for the passage of oil, which bore, within the transverse area of the enlargement 8, is diametrically increased at I8 throughout the remaining length upwardly of the feed pipe extension. The juncture of the respective diameters of the bore are formed to provide a valve seat I9 on which is positioned a valve, preferably a ball valve 29. The upper end of the bore enlargement I? is further increased in diameter at the upper end of the spout-receiving section I I, providing a narrow shoulder 2| to receive the upper out-turned ends 22 of a U-form cage 23, the cross bar 24 of which overlies the valve and prevents undue upward movement of the same during operation or in any desired position of the oiler. The cage is of course readily removable for access to the valve and seat when desired.

The cylinder I of the valve proper has secured to the outer surface thereof near the outer end a bifurcated hook 25, and a rod 26 extends through appropriate openings in the enlargement 4 of the handle and the bottom of the plug 5 and is reduced in thickness at its lower end, as at 21, to fit in the bifurcation in the hook, with the terminal 28 of the rod fitting in the bend of the hook to removably connect the rod and cylinder of the pump.

The handle proper includes an integral depending portion 29 which extends down free of and lengthwise the container, the lower end of the depending portion being preferably upturned to afiford a convenient handle grip. An operating lever 33 is mounted for rocking motion upon the horizontal portion of the handle, with the free or operative portion of the lever positioned for free manipulation by a finger of the hand gripping the handle grip. The inner end of the lever is formed with an elongated opening 3I through which the upper end of the rod 26 extends, the rod being headed to permit elevation of the rod and thereby upward movement of the cylinder of the pump proper against the usual return spring on depression of the outer end of the lever.

The invention contemplates a novel method of supporting the lever to provide for the rocking movement of the latter, and to this end the material of the horizontal portion of the handle is cut out in the form of a T and the material thus cut out is bent upwardly to provide a projection having an upright portion 32 extending upwardly at right angles to the horizontal portion of the handle and an upper terminal extending in both directions beyond the upright portion to provide end projections 33. The operating lever 30 is depressed at a point intermediate its length to provide a rocking or fulcrum point which bears upon the horizontal portion of the handle and this depressed portion of the lever is cut away, as at 34, in the form of a slot having a length corresponding to the length of the upper end portion of the projection 33, the central portion of the slot 34 being enlarged on more or less curved lines, as at 35, to permit a rotative movement of the neck or shank of the upstanding portion 32 of the handle.

The lever is assembled by passing the upper end portion 33 of the upstanding portion 32 through the slot 34, the lever in this position being at right angles to the handle portion. The lever is then turned into alignment with the handle portion, so that the enlarged upper end 33 of the upstanding portion 32 of the handle projection extends transverse the slot, with the lever aligned with the handle. The rod 26 is then passed through the opening 3! of the lever, the aligned openings in the handle enlargement 4 and the bottom of the plug 5, and engaged with the bifurcated hook 25 of the pump cylinder.

The spout 36 is of course removably connected to the spout-receiving section II, preferably by a coupling 31, suitable gaskets maintaining a tight connection.

The unitary formation of the feed'pipe and feed pipe extension to insure strength, prevent leakage and avoid the necessity of soldering or other connection tending to leakage or breakage is a practical and commercial advantage in oilers of this type as it not only simplifies the assemblage but it materially increases the strength and life of the oiler as a whole.
